NStar will soon begin its annual overhead visual inspections of electrical equipment on local rights-of-way, using a helicopter with a high-resolution camera. In some cases, the helicopter will hover over certain equipment for up to five minutes.
In a related effort, in April NStar completed separate overhead transmission inspections across its service area using heat-sensing infrared scanning equipment.
Current plans call for NStar’s inspections of the transmission lines to be completed on Cape Cod in June. Weather permitting, inspections are carried out seven days per week between the hours of 7 AM and 5 PM.
